Pull the plug that connects to the freqency valve and check the connections there. Someone had unplugged the FV on my car, but they pulled by the wire, not the boot.

Check the plug and push the wires back in if nessisarry. -Robert vin 6585 --- In dmcnews@xxxxxxxxxxx, Delorean17@xxxx wrote: > Hello List, > My car hasnt been running in about a month because my ECU went bad.
